I worked three jobs. Can I file for my tax return one by one within the same year or I should do them together?

All of your income for the year gets reported on the same return.

You HAVE to enter them on the same tax return.  So wait to get all your W2 and any 1099 forms.  If you file one first you will need to amend that return to add the others.  And you can't amend until much later after the IRS process the first return.
